DUPINT or DUP-CHL Alarms
As long as any alarms against either of these MOs persist, memory shadowin g
will not be turned on.
Standby PKT-INT Major Alarms
These prevent memory shadowing. See “PKT-INT”. It may be ne cessary to reset
the board (reset packet-interface).
Standby MEM-BD Major Alarms
These prevent memory shadowing. See “MEM-BD” .
When yo u obs erve a ny of t he ab ove p rob lems, first busy out th e sta ndb y SPE,
then fix the given problem (us ually with a lock-and-power- down replacement),
then release the standby SPE.
If any of the above problems p ersist, or if none of them appears but shadowing
remains off in the presence of good handshake, escalate the p roblem.
Resolving Refresh Problems
It can happen that hand shake communication and memor y shadowing can b oth
be ma intai ned t o a sta ndb y SPE, b ut for some r eason that SPE c anno t be
completely refreshed. In this c ase, one must distinguish b etween delays in
refresh completion and outrig ht failure. This section addresses the situation in
which shadowing remains on, hand shake remains up, but refresh will not
complete.
Delays in Refresh
Under extremely heavy occup ancy loads, standb y refresh can be delay ed but it
is still expected to c omplete within 10 minutes of the time when memor y
shadowing was turned on. You should not see delays greater than this without
some STB Y- SPE alar m .
Failure of Refresh
The refresh operation occurs in two steps:
■Refresh of Packet Interface dual port RAM (very q uick execution)
■Refresh of all memory on all memory boards
A fail ure c an oc cur i n eith er of these step s. When refre sh fai ls, STBY- SPE error
code 1281 is logg ed. The auxiliary data indic ates which aspec t of refresh failed.
Aux code 1383 indic ates that the memory board p art has failed. This typically
indicates a problem with
active
SPE memory circuit packs. Execute the long test
sequence against b oth active SPE memory circuit packs a nd see “MEM-BD”. If
